      "value": "Kiota is an OpenAPI based HTTP Client code generator. Prior to 1.29.1 and 1.32.5, `kiota info` read x-ms-kiota-info.languagesInformation.<language>.dependencyInstallCommand plus dependency name and version values from an OpenAPI description and presented the spec-supplied command as Kiota's recommended install command, allowing an attacker-controlled or compromised description to cause command injection when the suggested command was run manually or through the Kiota VS Code extension's kiota info --json dependency-install flow. This issue is fixed in version 1.29.1 and 1.32.5."

Antes de la versión 1.32.5, ’kiota info’ leía x-ms-kiota-info.languagesInformation.[language].dependencyInstallCommand más los valores de nombre y versión de la dependencia de una descripción OpenAPI y presentaba el comando proporcionado por la especificación como el comando de instalación recomendado de Kiota, permitiendo que una descripción controlada por un atacante o comprometida causara inyección de comandos cuando el comando sugerido se ejecutaba manualmente o a través del flujo de instalación de dependencias ’kiota info --json’ de la extensión de Kiota para VS Code. Este problema está solucionado en la versión 1.32.5."
